Backend & API Development
Systems that stay fast and maintainable after the first thousand users.
A backend that works on day one and a backend that still works at scale are different pieces of software. The difference is a handful of architecture decisions made early — how services are separated, how data is modelled, how failure is handled — and by the time the problem shows up in your response times, those decisions are expensive to revisit.
We build and repair backend systems in Python for products that need to grow. Clear service boundaries, APIs designed to be consumed rather than just to exist, test coverage on the paths that matter, and documentation the next engineer can follow without a handover call.
REST API design and implementation
Versioned, consistently structured, and documented.
Microservice architecture
Service decomposition, inter-service communication, and independent deployability.
Database design and optimisation
Schema design, indexing, query tuning, and safe migration strategy.
Authentication and authorisation
Token and session auth, role-based permissions, and third-party identity providers.
Legacy modernisation
Refactoring monoliths and untangling systems that have outgrown their original design.
- Can you work with our existing codebase?
- Yes, and often that's the engagement. We start with a short review so we can tell you honestly whether the right move is refactoring or rebuilding — those are very different budgets and you should know which one you're in before we start.
- Do you work alongside our existing team?
- Regularly. Embedded engagements where we take specific services or a defined slice of the roadmap tend to work better than parallel teams.
